К ВОПРОСУ ПОПОЛНЕНИЯ ПОПУЛЯЦИИ ЛОСОСЕВЫХ РЫБ НА ПРИМЕРЕ ЧЕРНОМОРСКОЙ КУМЖИ (SALMO TRUTTA LABRAX PALLAS, 1814)

Abstract

The article highlights the future development of salmon cultivation at the example of breeding bull-trout ( Salmo trutta labrax Pallas, 1814) inhabiting the Black Sea and Azov Sea. There has been made the analysis of key biotechnical processes of forming brood stock and reproduction of bull-trout in order to replenish the endangered fish population. The deficiency of producers, low abundance of the brood stock and, actually, a low number of bull-trout population (bull-trout is listed into the Red Book of the Krasnodar region and the Red Book of the Russian Federation) are the main limiting factors of the species reproduction. There has been given the review of the current state of species reproduction, as well as the analysis of the trout-breeding plant “Adler” efforts on reproduction and preservation of bull-trout population. In order to produce viable breed for further releasing into the natural habitat and replenishing population of this valuable species, as well as due to low ability to survive (13%) there have been given recommendations on using live feed such as gill-footed crustaceans Artemia salina along with artificial feed. The work on reproducing and forming the brood stock should become the main objective of the trout hatchery “Adler” over the medium term.
